The first pressed key on the kbd triggers the seq.
Impossible to set up the tempo neither on martster kbd, nor on the slaved Circuit.
If I'm not mistaken, Circuit uses Real Time midi Messages : FAH start, FBH stop, F8H timing clock. Not cc unfortunately ( only cc available are on the Keystep but also trigger a seq which is why I don't want to use the Keystep as BPM master ( also there's not screen on the Keystep, so it's impossible to know accurately what the BPM are )
I had forgotten to follow your advice about the fact that phi midiclock was a subpatch... checked and discovered there was a DIN/usb menu to set... set it up on usb.
By the way @philoop, phi clock also has a toggle?
So, Iv'e started to experiment with both your solutions, adding back some patches and subptaches but I end up each time stuck with the same issue :
whatever I try, best result is always : ok to play the notes while seq isn't playing, ok to trigger the seq from the Circuit using start, but impossible to modify the bpm from the Circuit ( which is the aim ) not from the master keybd....
I'm focusing first on this first thread and will gradually come back to the two others you've answered due to simply a lack of time this week
